Abstract
The utility model discloses an ejection-proof slip device, which comprises an ejection-proof joint and a pressure plate, wherein the pressure plate sleeves on the upper part of the ejection-proof joint; inner threads are formed on the upper part of the ejection-proof joint, and outer threads are formed on the lower part of the ejection-proof joint; an annular boss is arranged on the ejection-proof joint; a screw rod hole is formed in the two ends of the pressure plate respectively; screw rods are connected with a flange of a spray-proof device through the screw rod holes; the lower end of the ejection-proof joint is tightened with the outlet of the spray-proof device; a plug valve is arranged at the upper end of the ejection-proof joint, and is tightened with an oil outlet pipe in order to fix the oil pipe to the flange of the spray-proof device. By adopting the ejection-proof slip device, the oil pipe is effectively prevented from being ejected upwards, the labor intensity and the working risk are lowered, the working efficiency is increased, and the production benefit is increased.
Description
Technical field
The utility model relates to a kind of oil field device, relates in particular to a kind of anti-jack slips device.
Background technology
In oilfield exploitation, because oil field geologic differs, geological condition complexity, the oil of a lot of mining areas is poor, because bottom pressure is high, Gao Ning, high viscosity, in underground work process, very easily occur on oil pipe useful therefore, while particularly temporarily shut-down halfway, wash in kill-job construction and more easily occur pushing up on oil pipe, cause very large difficulty to underground work.On oil pipe, in the process of top, tubing coupling place easily damages ram block and seal, causes half envelope sealing malfunctioning, causes blowout and well-control equipment damage accident, and serious meeting is to causing casualties.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of anti-jack slips device of pushing up on oil pipe of can effectively preventing.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anti-jack slips device, comprise anti-apical grafting head, pressing plate, described pressing plate is enclosed within described anti-top upper end of joint, and described anti-top upper end of joint is provided with internal thread, lower end is provided with external screw thread, described anti-apical grafting head is provided with annular boss, and this annular boss is positioned at described external screw thread upper end, is provided with trepanning in the middle of described pressing plate, respectively there is a screw hole at these pressing plate two ends, and described annular boss external diameter is greater than described trepanning internal diameter.
As preferably, also comprise two screw rods, described screw rod runs through described pressing plate by described screw hole.
As preferably, described pressing plate is positioned at described annular boss upper end, and this pressing plate comprises left pressing plate, right pressing plate, and described left pressing plate is connected with described right pressing plate by bolt.
As preferably, also comprise snap ring, in the middle of described snap ring, be provided with bayonet socket, described snap ring comprises left snap ring, right snap ring, and described left snap ring and described right snap ring are bolted, and described snap ring is connected with described pressing plate by bolt.
The beneficial effects of the utility model are effectively to prevent from pushing up on oil pipe, have ensured job safety, have improved operating efficiency, have increased productivity effect, and simplicity of design is easy to make, is of value to popularization.
